IClaim.

The invention relates generally to metallic receptacles and primarily seeks to provide a simple and economically constructed can or metal container having a full open pouring throat from which the whole of the contents of the can may be poured, which is devoid of raw metal edges, and which includes a readily mountable and removable sealing closure including a resilient securing bead and clamp wire and lever equipment.

19 In its more detailed nature, the invention resides in the provision of a cylindrical can body having a full diameter discharge opening defined by an outwardly rolled resilient edge bead, and a generally flat cover having a sealing compound equipped peripheral groove for receiving said bead and 2. depending beaded flange which is slotted to form resilient sectors and equipped with a clamping wire and a clamp lever operable to contract the wire and they resilient sectors 9' which carry it so as to grip the resilient bead and draw the sealing compound equipped portion of the cover down into tight sealing contact with said bead.

with these and other objects in view which 5 will more fully appear, the nature of the invention will be more clearly understood by following the description, the appended claim, and the several views illustrated in the accompanying drawing. 7 In the drawing:

(Cl.-220-6l) container body thus formed is devoid of exposed raw metal edges, both inside and outside, and includes a full open pouring throat, that is its top portion is wholly open and free of obstruction throughout the entirety of its diameter, en- 5 abling removal of the whole of the contents of the container with great facility. 1 For cooperation with the resilient head i, I provide a novel cover which can be mounted or removed with great facility, and which, when 10 mounted, is capable of eiiectively sealing the container. The cover includes a generally flat body 8 mainly of irusto-conical shape terminating peripherally in an upstanding rib 9 which provides a downwardly directed groove ID dimensioned to overlie the can body head I and which is filled with a suitable sealing compound II intended toengage in sealing relation with said head. The outer wall of the frusto-conical portion of the cover constitutes the inner bound- 20 ary of thegroove 10 and it is located adjacent v to the inner side of head I so as to force the sealing means outwardly upon clamping the lid or cover to the body. The cover also includes a depending flange I2 for embracing the body 25 bead I, and the lower edge of this flange is rolled outwardly and upwardly as at l3 about a clamping wire I. A clearance or recess I5 is provided in the edge roll or bead l3, and the ,free ends of the wire ll extending into this clear- 30 ance are shaped in the form of oppositely or outwardly directed hooks l6, see Figures 1 to 3. It will be noted also by reference to these figures that the roll or bead I3 is notched or slotted at equidistantly spaced points, as at H, so as to 5 provide a plurality of resilient cover edge sectors l8 which will be contracted whenever the I hooked ends l6 of the wire M are drawn together, and which will expand whenever the tension in the wire is relaxed. 40

For suitably manipulating the wire I4 and the resilient sectors l8 in which it is encased, I provide a cam lever formed of a single piece'of wire shaped to include a bridge piece l9 merging with apairoflaterallyspaceiangularlydisposedu cam eyw 20 each encircling one of the wire hooks l6 and which in turn merge into a finger piece or handle portion 2|.

My improved container is adaptable to use ples of which are syrup, oysters, crab meat, paint, candy, peanuts. pastes and polishes. The provision of the resilient, outwardly turned bead not only facilitates mounting and replacement of the cover, and the attainment of an efllcient ofnumerous products, 'examso 2 seal, but it entirely eliminates the presentation of raw metal edges and provides a full open discharge or pouring throat throug which the entire contents of the container can be removed with facility.

In the use oi the container, the cover is placed onthe body with the oam lever in the position shown in Figs. 1 and 4, that is with the wire II in the tension relaxed state and with the resilient cover edge sectors i8 expanded. See Figs. 4 and 5. It will be noted that in this condition of the parts the sealing compound ring ll rests lightly upon the resilient head I and the axis of the wire I4, or of the resilient sectors I8, lies in a planexbelow that occupied by the axis of the resilient head 1. By now turning the cam lever.

down to the position shown in Fig. 6, the hooks It will be moved toward each other, placing the wire H under tension and contracting the resilient cover sectors i8 beneath the resilient head I. The cover is thus firmly secured in place and is drawn down tightly upon the head I so as to compress the sealing compound about the bead and effect a perfect seal.

The novel relation of the bead I, the sealing compound equipped groove l0 and the resilient sectors l8 assures perfect sealing of the container and enables mounting and removal of the cover with great facility. The resilient quality of the head I constitutes a major factor in the provision and maintenance of the seal since it aids materially in attaining and maintaining conformity of the sealing surfaces. It will be noted that the flange slots I'I' do not extend above the base plane of the cover body 8 and thus do not disrupt the continuity of the sealing compound receiving groove in.

What I claim is:

A containerot the character described comprising a sheet metal body terminating at its upper end in an outwardly rolled resilient head,

a cover comprising a generally flat body portion 6 terminating'peripherali-y in a raised rib forming a groove positioned to overlie "the body head and a depending flange of a diameter for em-- bracing said body bead and terminating in an outwardly rolled cover bead having a clearance at one portion thereof, a clamp wire encased in said cover bead ,and having free ends disposed in said clearance, sealing means disposed in said groove, the inner boundary of said roove being positioned adjacent the inner side of the first 15 mentioned bead and comprising a downwardly and inwardly sloping irusto-conical wall coacting with the head on the body and with the said sealing means to force said sealing means outwardly upon clamping the cover to said body, said cover flange depending to an extent serving to dispose the cover bead axis in a plane spaced only slightly below that in whichthe body bead lies whereby the upper limit of the cover bead is disposed in a plane above that occupied by 25 the lower extremity of the body bead, and lever means secured to said ends and movable between cover clamping and releasing positions in which the wire is tensioned or relaxed respectively to grip the cover bead about the body bead and'30 draw the cover down upon the body head in clamped position so as to compress the sealing means about the body head or release said cover bead from gripping relation with said body bead.
